Abstract

A network system of a radio system includes procedures and apparatus for updating, by means of which the usage parameters of a subscriber station are updated prior to a hard handoff, so as to be suitable for a connection intended to be in effect subsequent to the hard handoff. The network system also includes procedures and apparatus for assisting a hard handoff for selecting, on the basis of the results of measurements of a pilot signal, a best base station as a handoff candidate to which the hard handoff is performed when necessary. The network system also has procedures and apparatus recovery for reserving and recovering the initial connection of the subscriber station to the base station in case a hard handoff fails. Connection losses in hard handoff and interferences caused by the wrong transmitting power are thus reduced.
